Procure from strange tradesman (3)
I believe the answer is:
get
'procure' is the definition.
(I know that procure is a more specific form of capture)
'from strange tradesman' is the wordplay.
'from' indicates a hidden word.
'GET' is hidden in the letters of 'strange tradesman'.
(Other definitions for get that I've seen before include "Escape" , "Understand" , "Acquire" , "Procure or secure" , "Procure from vegetables" .)
